Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Summarize the importance of electrolytes from this article.

What is an electrolyte panel?

Electrolytes are electrically charged minerals that help control the amount of fluids and the balance of acids and bases in your body. They also help control muscle and nerve activity, heart rhythm, and other important functions. An electrolyte panel, also known as a serum electrolyte test, is a blood test that measures levels of the body's main electrolytes:

Sodium, which helps control the amount of fluid in the body. It also helps your nerves and muscles work properly.
Chloride, which also helps control the amount of fluid in the body. In addition, it helps maintain healthy blood volume and blood pressure.
Potassium, which helps your heart and muscles work properly.
Bicarbonate, which helps maintain the body's acid and base balance. It also plays an important role in moving carbon dioxide through the bloodstream.
Abnormal levels of any of these electrolytes can be a sign of a serious health problem, including kidney disease, high blood pressure, and a life-threatening irregularity in heart rhythm.

Other names: serum electrolyte test, lytes, sodium (Na), potassium (K), chloride (Cl), carbon dioxide (CO2)
Response: Electrolytes are important because they control the balance between acids and bases in your body, as well as the amount of fluids. They help control many of the body's vital functions, like heart rhythm and nerve and muscle activity. An abnormal level of electrolytes can indicate a serious or life-threatening health problem. 

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

What are the main functions of the human respiratory system?

The human respiratory system is responsible for taking in oxygen and expelling carbon dioxide. The main functions include facilitating gas exchange in the lungs, maintaining proper oxygen levels in the blood, and removing waste gases like carbon dioxide.
